A phase converter is a device that produces three-phase electrical power from a single-phase source, allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
The first phase converters were invented nearly one hundred years ago. Static phase converters have changed little since that time. Since then, new types of phase converters have been developed, driven by the available technology and the needs of ever more modern equipment.
A large number of applications and equipment once considered "industrial" require three-phase power. The general use of three-phase equipment is increasing on farms and ranches, in home wood and metal shops, or in other locations where utility-provided 3-phase isn't readily available. Even when 3-phase is available nearby, the costs of bringing in new service, adding additional transformers and wire can drive costs upward of $50,000.
Phase Technologies manufactures modern and highly efficient digital phase converters and variable frequency drives (VFD's) for virtually any application. Use the following guide to determine what the best solution is for your use-case. If you need help or have questions please call our expert sales staff for assistance.
For loads such as CNC, HVAC, and elevators, a Phase Perfect® Digital Phase Converter is recommended.
Read common questions and answers about phase convertersThree-phase power as good as the utility provides. In many cases you can get away without having perfect three-phase power and still get the job done. Those applications are becoming fewer and fewer, however. Power efficiency mandates, smart or internet connected devices, and modern safety features mean computers are being embedded in more and more devices where you may not have expected to find them in the past. Running these devices on a Phase Perfect® will ensure they run as well as they would with utility three-phase and protect these delicate embedded electronics.

VFD's are becoming the standard for pumping because they allow you to take advantage of variable speed, soft starting and stopping, constant pressure water systems, and advanced pump and well protection features.
